Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a belt sleeve demolding apparatus and a belt sleeve demolding method for extracting a vulcanized belt sleeve from a mold.

[0002]

2. Description of the Related Art As a conventional belt sleeve removing device, there is known a device described in Japanese Patent Application Laid-Open No. 2000-85027. A belt sleeve demolding device is composed of a plurality of belt retainers for holding an integral body of a belt sleeve (same as a belt slab) and a mold from the outer periphery of the belt sleeve, and holding the belt sleeve in a state in which the mold is aligned with a mold axis. Moving means for pushing up in the direction.

[0003] The removal procedure by this belt sleeve removal device is performed by suspending and moving the integrated body of the belt sleeve and the mold using an elevator such as a crane to move the table of the moving means from between the belt pressers. Place on top. The outer periphery of the belt sleeve is immovably held by extending the hydraulic cylinder constituting each belt retainer.

Subsequently, the hydraulic cylinder constituting the moving means is extended and the table is raised, thereby pushing up the mold and removing the belt sleeve from the mold. The mold from which the belt sleeve has been removed is suspended and moved using a lift such as a crane, and is carried out to the vulcanization molding machine. Further, the belt sleeve is taken out by releasing the holding by each belt retainer.

[0005]

In the conventional belt-sleeve removing device, the belt sleeve is pressed from the outer periphery by hydraulic cylinders provided at four positions at equal angles. If the dimensional relationship with the belt retainer is as shown in FIG. 2 of the publication, it works without any problem.However, when a belt sleeve having a larger diameter is to be extracted or a thin belt sleeve is to be extracted. In this case, the pressing force and area of the belt press are insufficient.

[0006] In this case, the belt sleeve cannot be removed from the mold satisfactorily, and it takes time to re-press the belt sleeve many times. Further, if the pressing portion is too short, there is a possibility that the belt sleeve may be cracked or torn, and there is room for improvement in a demolding device and demolding method that can cope with belt sleeves of various diameters. .

Further, in the above-mentioned prior art, an elevator such as a crane is used as a means for moving the mold from which the belt sleeve has been removed and carrying it out to a vulcanization molding machine or the like. In this case, after the mold is lifted and removed by the moving means, the raised mold is hung on a hook or the like, and then the mold in the hung state is moved, so that the process sequence is as follows. It takes a long time to carry out the mold by means of an elevator or the like from the rise of the mold, which tends to take a long time, which is not very favorable in terms of work efficiency. In particular, when removing a large belt sleeve, it takes a long time to carry out the mold.

[0008] An object of the present invention is to make it possible to smoothly remove the belt from the mold even if the diameter of the belt sleeve is large or small, or to carry out the mold withdrawal operation after the belt sleeve is released from the mold more quickly. By improving the working efficiency, it is possible to provide a belt sleeve demolding apparatus and a belt sleeve demolding method capable of coping with a wide diameter of the belt sleeve and a wide diameter from a large diameter to a small diameter of the belt sleeve. is there.

[0016]

According to the first aspect of the present invention, a plurality of pressing members are moved by pressing or extending the pressing members, and a larger number of pressing members than the number of pressing members in the small operating state are moved to reduce the number of pressing members. Since a large number of operation states in which the belt sleeve has a larger diameter than the belt sleeve depending on the operation state can be selected and set, a small number of pressing members act on a belt sleeve having a small diameter and a large diameter. A large number of press members act on the belt sleeve. Thereby, the ratio of the length of the pressing member acting in the circumferential direction of the belt sleeve to the circumferential length of the belt sleeve is set to be the same or close to the same value regardless of the diameter of the belt sleeve. It becomes possible to do.

As a result, the mold is moved from the first position to the second position without inconvenience, such as re-gripping the belt sleeve many times, or distortion between a portion where the pressing member acts on the belt sleeve and a portion where it is not. Irrespective of the diameter of the belt sleeve, it is possible to effectively maintain the belt sleeve at the first position regardless of the forced movement of the belt sleeve.

According to the second aspect of the present invention, the transfer means for receiving the mold moved to the second position and carrying it to a position other than the first position, and the movement of the mold to the second position are completed. Since the interlocking means for performing the receiving operation of the mold by the transporting means is provided, when the mold is moved to the second position, the transporting means is already in the condition that the mold is suspended by the hook. The mold is ready to be transported, and the mold can be immediately transported to a position other than the first position. In other words, compared to a case where the mold is moved to the second position, a receiving operation of the conveying means such as hooking the mold is performed, and then the carry-out by the conveying means is started, Since the time for the receiving operation can be omitted, the time can be reduced accordingly.

According to the third aspect of the present invention, the moving means for forcibly moving the mold is provided by moving the mold from the first position to the second position above the first position.
Since it is configured to be raised to the position, for example, as compared with a case where the die is forcibly lowered from the first position to the second position below the first position, the position for loading the die having the belt sleeve is lower. The labor and power required for carrying in can be reduced. And the second located above one position
Since the transport means of the mold raised to the position is suspended and carried out in the horizontal direction, the mold already raised to a high position can be quickly carried out with a short moving distance. The interlocking means for engaging the hanging hook with the mold before the elevation of the mold to the second position is completed, includes an engaging mechanism for engaging the hook with the mold. Since the ascending speed is the same as the ascending speed to the two positions, the following operation is obtained.

That is, when the hook is engaged when the mold is in the first position, the hook suspending member such as a wire can be pulled up without loosening, and then the moving means can be used. Even if the mold is released, the suspended state can be maintained at the same position without dropping once. Further, when the hook is engaged while the mold is raised from the first position to the second position, the state where the relative position between the hook and the mold does not change is maintained. The mold can be smoothly and satisfactorily suspended by merely engaging the hook without using the mold.

According to the fourth aspect of the present invention, since the belt moving means for moving the belt sleeve extracted from the mold from the first position to the second position is provided, the mold is carried out from the second position. Similarly to the above, the belt sleeve can also be moved to the second position and shifted to the state of being carried out, and both the separated mold and the belt sleeve are removed, and the mold of the next mold having the belt sleeve is removed. Preparations for performing the sampling step can be prepared.

The first elevating cylinder 3 is the first position (set position) where it is most shortened, and the second position (the most extended position). The mold 2 can be moved up and down over the transfer position).

As shown in FIG. 1, FIG. 2, and FIG. 6 to FIG. 8, the holding means 4 is a radial hydraulic pressing cylinder (moving mechanism) centered on the mold center P at the set position of the mold 2. Example of b) Twelve of 14, 15, and 16 are supported by a ring-shaped mounting frame 28 in a plan view, so that they are arranged in a recumbent posture and in a state of expanding and contracting inward. . The twelve hydraulic cylinders 14 to 16 include four first pressing cylinders 14 having a short operating stroke, four third pressing cylinders 16 having a long operating stroke, and a first cylinder 14 and a third cylinder having operating strokes of three. 16
And four second pressing cylinders 15 set in the middle of the first to third pressing cylinders 14 to 14.
16 are alternately arranged adjacent to each other.

Each of the pressing cylinders 14 to 16 is connected to an end surface 14a, 15
The positions of a and 16a are arranged on a single circumference so as to have the same diameter with respect to the mold center P, and in the standby state (the shortest state), each piston rod 14A, 1
The action parts (an example of the pressing part a) 14S, 15S, 16S attached to the tips of 5A, 16A are arranged on the same circumference as each other (see FIG. 2). Then, the twelve pressing cylinders 14 to 16 are configured to start the extension drive at the same time, and the action portions 14S to 16S abut against the pressing object (in short, the outer periphery of the belt sleeve BS) to perform a predetermined operation. Is controlled so that the extension drive is automatically stopped when the load of.

Accordingly, when the outer diameter of the belt sleeve BS is equal to the first working portion 1 when the first pressing cylinder 14 is fully extended.
When the diameter is larger than the diameter connecting the 4S, as shown in FIG. 6, all of the twelve working portions 14S to 16S press and hold the belt sleeve BS. Belt sleeve BS
Is less than or equal to the diameter connecting the first working portions 14S when the first pressing cylinder 14 is fully extended, and connecting the second working portions 15S when the second pressing cylinder 15 is fully extended. When the diameter is larger than the diameter, as shown in FIG.

When is larger than the diameter connecting the third action portions 16S when it is fully extended, as shown in FIG. 8, the state is such that the gripping action is performed only by the four third action portions 16S by the third pressing cylinder 16. In other words, the outer diameter of the belt sleeve BS is smaller than the diameter connecting the operating portions 14S to 16S when all the pressing cylinders 14 to 16 are at the standby position, and
In a range larger than the diameter connecting the third action portions 16S when the third pressing cylinder 16 is fully extended, the gripping action by the gripping cylinders 14 to 16 according to the outer diameter of the belt sleeve BS in that range. 12 places and 8 places
It is configured to be automatically selected and set from three types of locations and four locations.

If the case where the diameter of the belt sleeve BS is small and the number of working portions required for gripping the belt sleeve BS is four, ie, the third working portion 16S, is defined as a "small number of working states", the action required for gripping the belt sleeve BS. In the case where the number of parts is eight, that is, four of the third action part 16S and four of the second action part 15S,
The case where all of the twelve action portions 14S to 16S perform the gripping action is the “multiple action state”. Also, belt sleeve B
If the diameter of S is medium, and the number of action parts required for gripping is eight, that is, four pieces of the third action part 16S and four pieces of the second action part 15S, the "small action state" , Only when all of the twelve action parts 14S to 16S perform a gripping action, is the "multiple action state". As shown in FIG.
Is a first lifting cylinder 3, a plurality of second lifting cylinders 8,
And a hydraulic unit 17 for the first to third pressing cylinders 14 to 16 and an inverter 19 for a drive unit (to be described later) 18 of the overhead crane 6 to control the operation, and to smoothly operate each process. It has a function of controlling each part so that smooth transfer between processes is realized.

As shown in FIGS. 1, 2, and 4, the overhead crane 6 includes a track rail 20 made of an H-shaped steel or the like extending laterally at a ceiling position and a suspended state on the track rail 20. It is composed of a crane body 21 that can move and travel, and a crane hook 9 that is suspended from the crane body 21 so that it can be driven up and down. The crane body 21 has a pair of right and left and front and rear traveling rollers (not shown), a traveling motor (not shown) capable of driving and rotating them, and the hook 9 by winding and unwinding the wire 22. Driving unit 1 equipped with a vertically movable motor (not shown)
Eight.

The overhead crane 6 carries the mold 2 having the belt sleeve BS from the outside by lateral movement, and then carries it down to the set position by lowering it, and is raised to the second position to remove the belt sleeve BS. After the mold 2 is lifted, the carry-out movement is performed in which the mold 2 is laterally moved so as to be transferred to the next k step. During the carry-in movement and the carry-out movement, the hook 9 is kept engaged with the hoist portion 12 of the mold 2.

The hook 9 is engaged with the hoist portion 12 by, for example, the side hole 1 formed in the side surface of the hoist portion 12.
Various means such as a connecting means for inserting a slidable pin provided on the hook 9 into the hook 9a, a suction means by an electromagnet, and a gripping operation of the hoist portion 12 by the hook 9 are possible. Not done.

As shown in FIG. 1, the interlocking means 7 lifts and moves the hook 9 engaged with the hoist portion 12 at the same speed as the rising speed of the mold 2 by the extension operation of the first lifting cylinder 3. And is constituted by the control unit 5. That is, the hydraulic unit 17 that controls the operation of the first lifting cylinder 3 and the drive unit 18 of the overhead crane 6 are controlled so that the hoisting speed of the hook 9 matches the extension speed of the first lifting cylinder 3. By this control, when the mold 2 is raised to the second position, the wire 22 is slackened, and when the first lifting cylinder 3 is driven to be shortened, the wire 22 is suddenly tensioned to cause a hanging shock, or the horizontal transport is performed. Rewinding to a suitable height position prevents the cycle time from being delayed.

As shown in FIGS. 1, 4 and 5, the second lifting cylinder (an example of a belt moving means) 8 is disposed at a position on the circumference corresponding to the diameter of the belt sleeve BS at an equal angle. (Or four or more) are arranged in a vertical position, and are provided with a perforated disk-shaped pedestal 2 provided at the tip of the piston rod 8A.
The support sleeve 3 supports the end surface of the belt sleeve BS. A belt sleeve BS is placed on
The roller conveyor 24 or the free roller that can rotate in any direction is incorporated in the moving direction toward the moving direction, and the belt sleeve BS is mounted on the roller conveyor 24 or the free roller.

Next, the details of one cycle process from carrying in the mold 2 with the belt sleeve by the belt sleeve removing device 1 to carrying out the mold 2 and the belt sleeve BS after separation will be described. Note that “after separation” means “after the belt sleeve BS has been removed from the mold 2”.

First, all the cylinders 3, 8, 14 to 16
In the standby state where is minimized, the mold 2 with the belt sleeve is laterally transported from outside the apparatus to a position directly above the first lifting cylinder 3 by the overhead crane 6, and then the hook 9 is moved.
And a preparation process is performed in which the tapered groove 2A at the lower end of the mold 2 is fitted into the tapered projection 3a at the tip of the piston rod 3A of the first lifting cylinder 3 (see FIG. 1).

Next, all of the twelve first to third pressing cylinders 14 to 16 are extended and driven, so that all or a part of the first to third working portions 14S to 16S are fixed on the outer circumference of the belt sleeve BS. The first step of pressing and holding with pressure (see FIGS. 6 to 8) is performed. In the first step, a selection setting step is performed in which the number of the working portions 14 to 16 pressed and moved to the outer peripheral portion of the belt sleeve BS is automatically set to a small value in synchronization with the diameter of the mold 2. In claim 5, this is described as "first
The process has a selection setting process. "

When the belt sleeve BS is firmly gripped so as not to move, the first elevating cylinder 3 is driven to extend, and only the mold 2 at the first position T1 is forcibly lifted. A second step of raising the position to the position T2 is performed (see FIG. 4). At this time, even when the movement of the mold 2 to the second position T2 is completed, the hook 9 of the overhead crane 6 is kept engaged with the hoist portion 12 and the wire 22 is
There is also a receiving step of maintaining a slightly slackened state. The mold 2 that has been lifted to the second position T2 and is in a standby state of being lifted by the wire 22 is further lifted and raised by a predetermined distance by the wire 22 of the overhead crane 6, and then moves laterally to carry out the transport path C (see FIG. 2). ) And carried out to the next process. In the receiving step, the mold 2 is lifted by the overhead crane 6 with the wire 22 slightly slackened, and the reception of the mold 2 from the upper second position T2 to the overhead crane 6 is quick and continuous. It is done on a regular basis.

When the mold 2 at the second position T2 is lifted again in a state of being suspended by the hook 9, the first lift cylinder 3
Is moved back to the standby position by shortening the length of the belt sleeve BS, and the second lifting cylinder 8 is driven to extend to move the belt sleeve BS extracted from the mold 2 from the first position T1 to the second position T2. (See FIG. 5). Then, the separated belt sleeve BS at the second position T2 is carried out of the apparatus to be transported to the next process through the transport path A by a carrying-out means (not shown), and the second lifting / lowering cylinder 8 is shortened and driven to the standby position. Return to

This completes one cycle of the belt sleeve demolding process. The next one cycle starts after the crane body 21 moving outside the apparatus carries in the next mold 2 with a belt sleeve. Is started.

[Alternative Embodiment] When the thickness of the belt sleeve BS is large or when the belt sleeve has high rigidity, the position holding means for locking and maintaining the belt sleeve BS at the first position is replaced with the flange portion 11 of the mold 2. The pressing member such as the action portion 14S may be extended and moved between the belt member BS and the upper end of the belt sleeve BS, that is, the pressing member may be extended and moved to a position facing the end face on the second position side.

In the above-described embodiment, the gripping portion of the belt sleeve BS has a relatively simple structure in which the three types of pressing cylinders 14 to 16 having different stroke amounts are simultaneously expanded and contracted. This is convenient because it does not require special operations automatically set to three types in synchronization with each other. For example, based on detection means for detecting the diameter of the belt sleeve BS and detection information of the detection means, Change and set the number of pressing cylinders to be gripped,
Control means. In addition, a first gripping device that presents a small number of operating states and a second gripping device that presents a large number of operating states are prepared, and one of the gripping devices is selected based on the diameter detection information of the belt sleeve BS. It is also possible to use a configuration that can be switched freely to be deployed.
In claim 1, these various means are collectively referred to as "a small number of operating states in which a plurality of pressing members are pressed or extended, and a number of pressing members larger than the number of pressing members in the small number of operating states are moved. Thus, a multi-action state in which the belt sleeve has a larger diameter than the belt sleeve in the few-action state can be selectively set. "

The mold moving means 3 for forcibly moving the mold 2 from the first position T1 to the second position T2 may be constituted by an overhead crane 6 with an improved output. Further, an electric cylinder may be used.

There are various relationships between the first position T1 and the second position T2, such as when the mold 2 is forcibly lowered (the second position is lower than the first position), when it is forcibly moved in the horizontal direction, when it is pressed diagonally, and so on. Things are conceivable.

According to the belt-sleeve releasing device according to the first aspect and the belt-sleeve releasing method according to the fifth aspect, the number of pressing members for locking and maintaining the belt sleeve in the first position is reduced. Even if the diameter of the belt sleeve is variously changed from a large diameter to a small diameter, or even if it is a thin belt sleeve, the holding member can be used to change the belt sleeve. The belt sleeve can be pulled out satisfactorily without inconvenience such as taking a long time due to failure to grasp or causing the belt sleeve to be distorted due to insufficient action of the pressing member.

In the belt-sleeve removing apparatus according to the second aspect and the belt-sleeving removing method according to the sixth aspect, when the mold is moved to the second position, the conveying means has already conveyed the mold. Since the preparation has been completed, the mold moved to the second position can be immediately carried out to a position other than the first position. , That is, the efficiency of the work process can be improved.

According to the belt-sleeve removing device of the third aspect and the belt-sleeve removing method of the seventh aspect, the labor and power required for carrying in the mold having the belt sleeve can be reduced. Since the mold raised to the two positions is suspended and carried by the transport means for laterally moving the mold, there is no waste in the movement of the mold, and the mold from which the belt sleeve has been removed can be moved to the next process quickly and efficiently. At the same time, the interlocking means can omit a dedicated process and a time for applying a hook to the mold, and can further improve the efficiency of the working process.

According to the belt-sleeve removing device according to the fourth aspect and the belt-sleeving removing method according to the eighth aspect, the effects of the first to third aspects or the fifth to fifth aspects are provided.
7 has one of the effects described above, and has the following effect. In other words, since the belt sleeve extracted from the mold can be moved from the first position to the second position in the same manner as the mold, the discharge movement path of the mold can be used without providing a discharge movement path dedicated to the belt sleeve. While being rational, the belt sleeve after separation can be quickly discharged and moved to the next process, which contributes to a smooth extraction work process.
